What the Down Payment Calculator does

The cash you need to buy is the down payment plus closing costs, which people routinely forget. Reaching 20% matters because it typically removes mortgage insurance, so the jump from 15% to 20% often pays for itself quickly.

Formula

Down payment = Price × Down payment percentage
Total cash needed = Down payment + Closing costs
Loan-to-value = (Price − Down payment) ÷ Price × 100

Worked example

A $350,000 property at 20% down with 3% closing costs, $40,000 saved, $1,500 a month at 4%.

Price: 350000
Down: 20
Savings: 40000
Monthly: 1500
Rate: 4

Down payment $70,000 plus $10,500 costs = $80,500. With $40,000 saved, about 25 months of saving remain.

Frequently asked questions

Is 20% down always best?

Not necessarily. Buying sooner with 10% can beat waiting two years if prices rise faster than you save. Weigh mortgage insurance against the cost of delay.

What do closing costs include?

Legal fees, survey, lender fees, title insurance and transfer taxes. They vary widely by jurisdiction — stamp duty alone can exceed 5% in some markets.
